Abstract
The Lap-joint configuration and the vacuum assisted forming method were put forward to meet the demands of the compression bending strength and the strong connection between the steel and FRC. The bending mechanic tests of the Lap-joint bending specimens carried out, the fabricate processing stability, limit carrying capacity and failure modes were analyzed. The experimental results show that the fabricate processing of the Lap-joint is stable; the bending stiffness is 19.5 N/mm, and the limit bending moment reaches 318 N∙m. The main failure modes are the failure of core material at junction of sandwich plate and steel, and the bending failure in the position of the inner and outer surface.
